Hmm .. it doesn't say anything.. except Schedule A in one while the other is blankI got this ADR too last week, but they specifically asked for paystubs, proof of income and if I filed tax returns. So I think that question is just a lead/summary of the documents to specified below in the ADR.
Check your application where you are meant to upload the documents, that might help give some clarity. I only had three fields which were the paystubs, income and tax returns.
Also, I have received 5 ADR requests. When I login, I see 2 placeholders to upload docs while other times I see 4. Guessing this a glitch?
